ABSTRACT:
The invention relates to an apparatus for agglomerating and precipitating suspended matter out of a gas using centrifugal acceleration within a treatment chamber distinguished by an inner cylindrical inlet tube through which the contaminated gas is led in a downward path and an outer circumscribing barrel through which the cleansed gas is led in a spiralling upward path. The inlet tube and barrel are mounted over and relative to a lower water filled reservoir or contaminant collection chamber. The gas exits from the inlet tube through an accelerator in the form of an adjustable venturi throat defined by a shroud arrangement vertically aligned with and spaced from the inlet tube and by which the downward flow direction of the gas is reversed as the gas aspirates water and passes upwardly through and out of the venturi throat and into the passageway defined by the inner inlet tube and the outer barrel. The upwardly moving gas is spirally deflected by means of spaced deflector plates outboard of and peripherally of the inlet tube and shroud so that a swirling motion is imparted thereto. The resultant force throws any heavy moist particles against an annular demisting collar which extends horizontally and radially outwardly into the path of the gas moving through the accelerator. The heavy mist impinging on the collar causes deflection thereby against the barrel wall whereby it is removed from the effluent and flows downwardly returnably to the water reservoir. The lighter mist-free gas bypasses the collar and moves in swirling fashion upwardly toward the clean gas outlet located within the upper part of the barrel, the gas picking up heat from the innermost inlet tube in its ascent and thereby assuring its mist-free condition upon reaching the gas outlet.
